BACKGROUND:Functional recovery after joint arthroplasty is an important indicator to evaluate the effect and prognosis of total knee arthroplasty, and is affected by patients and many kinds of outside factors. OBJECTIVE:To investigate the influencing factors of functional recovery of knee in patients with knee osteoarthritis after total knee arthroplasty. METHODS:Clinical data of 76 osteoarthritis patients undergoing total knee arthroplasty in the Dongying People’s Hospital from August 2007 to August 2013 were retrospectively analyzed. Hospital for Special Surgery knee score, knee pain Visual Analogue Score, range of motion and posterior slop angle of tibial plateau were compared before and 6 months after surgery. Changes in anterior condylar offset were recorded before and after femoral prosthesis arthroplasty. SPSS 21.0 software was used to analyze the influential factors for Hospital for Special Surgery knee scores after arthroplasty. RESULTS AND CONCLUSION:(1) Hospital for Special Surgery knee score, knee pain Visual Analogue Score, and range of motion were significantly higher 6 months after arthroplasty than that before arthroplasty (P<0.05). (2) Pearson correlation analysis demonstrated that preoperative Hospital for Special Surgery knee score, preoperative knee pain Visual Analogue Score, preoperative range of motion, preoperative posterior slop angle of tibial plateau and preoperative and postoperative anterior condylar offset changes were positively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). Body mass index and inversion deformity angle were negatively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). (3) Multiple linear regression analysis showed body mass index was negatively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). Preoperative Hospital for Special Surgery knee score, preoperative knee pain Visual Analogue Score and preoperative posterior slop angle of tibial plateau were positively correlated with postoperative Hospital for Special Surgery knee score (P<0.05). (4) These results indicated that total knee arthroplasty significantly improved knee joint function. Body mass index, preoperative Hospital for Special Surgery knee score, preoperative knee pain Visual Analogue Score, preoperative posterior slop angle of tibial plateau and preoperative and postoperative anterior condylar offset changes were correlated with the recovery of joint function after total knee arthroplasty.

Objective To investigate the effects of comprehensive psychological intervention on psychological and biochemical indexes of servicemen in three degree combat readiness. Methods 189 servicemen in three degree combat readiness were randomly divided into the study group and the control group by squad. Beyond the same exercise and education as the control group, the study group received the comprehensive psychological intervention in the course. They were all assessed with Self-rating Depression Scale (SDS) ,self-rating anxiety scale (SAS) ,and simplified coping style questionnaire (SCSQ) at the day entering three degree combat readiness (prereadiness) and the next day after the mission (post-readiness). The serum concentrations of superoxide dismutase ( SOD), malondialdehyde ( MDA), cortisol ( COR), and aldosterone (ALD) were determined to evaluate biochemical indexes at the same time. Results Compared with the control group after the combat readiness, the total scores of SDS( (42.1 ± 9.3 ) vs (49.2 ± 10.3 ) ) and SAS( (43.8 ± 7.2) vs (50.6 ± 10.2), P＜ 0. 01 ) were lower, the score of the positive coping style ( ( 21.2 ± 6.4) vs ( 18.2 ± 5.4), P ＜ 0. 05 ) was higher in the study group.Meanwhile,the levels of MDA( (2.6 ±0.51 ) μmol/L) ,COR( (252.5 ±52.4) ng/ml) ,and ALD ( (97.5 ±24.4) pg/ml) were lower ( P ＜ 0. 01 ), the activity of SOD ( ( 1551 ± 354 ) U/gHb) was higher ( P ＜ 0. 01 ) after the combat readiness. In the control group post-readiness, the total scores of SDS (49.2 ± 10.3) and SAS (50.6± 10.2) ,the levels of MDA ( (2.9 ±0.35 ) μmol/L) ,COR( (333.8 ±62.6) ng/ml) ,and ALD( ( 123.8 ±29.6)pg/ml ) increased significantly (P＜0.01), the score of the positive coping style ( 18.2 ± 5.4) and the activity of SOD ( 1302 ± 352 ) U/gHb decreased significantly ( P ＜ 0. 01 ). The total scores of SDS, SAS were negatively related to the level of SOD ( r= -0. 142, -0. 119, P＜0. 0lor 0.05) ,and positively related to COR ( r=0. 156,0. 159, P＜0. 01 ) and ALD ( r=0.151,0.156, P＜0. 01 ). The score of positive coping style was positively related to the level of SOD ( r=0. 141, P＜0. 01 ) ,and negatively related to COR and ALD ( r= -0. 152, -0. 155, P＜ 0. 01 ). Conclusion Comprehensive psychological intervention could effectively improve the psychological and biochemical indexes,reduce the stress level of servicemen in three degree combat readiness.

Objective To identify the metabolite levels and to study the potential effects of risporidone tablets on prefrontal lobe and thalamus in male first-episode schizophrenia by proton magnetic resonance spectroscopy (1H-MRS).Methods Twenty-two male first-episode schizophrenics were examined at prefrontal lobe and thalamus by multi-voxel 1H-MRS before and after 8 weeks' risperidone tablets treatment,and 30 normal controls were assessed once.The patients were also received positive and negative syndrome scale(PANSS) and Wisconsin card sorting test (WCST) before and after treatment.The N-aeetylaspartate ( NAA ),Choline-congtaining compounds (Cho),and Creatine compounds (Cr) were measured and the ratios of NAA/Cr,Cho/Cr were determined.Results On left prefrontal lobe and left thalamus,the NAA/Cr ratio in patients before treatment demonstrated lower than those in normal controls ( ( 1.37 ± 0.33 ) vs ( 1.61 ± 0.38 ),t =2.57,P ＜ 0.05 ; ( 1.46 ± 0.35 ) vs ( 1.71 ± 0.38 ),t =2.36,P ＜ 0.05 ).There were no significant differences in both the ratios of NAA/Cr and Cho/Cr between pre- and post-treatment (P＞0.05 ).The changes of NAA/Cr on left prefrontal lobe post-treatment were negatively related with the alterations of the total score of PANSS ( r =- 0.46,P ＜ 0.05 ),the score of negative symptoms ( r =- 0.48,P ＜ 0.05 ),the responses errors ( r =- 0.42,P ＜ 0.05 ) and the porseverative errors ( r =- 0.40,P ＜ 0.05 ),meanwhile,positively related with the alterations of the categories completed ( r =0.44,P ＜0.05 ) and the conceptual level responses ( r =0.42,P ＜ 0.05 ).Conclusions Abnormalities in neuronal function and/or integrity presented on prefrontal lobe and thalamus maybe exist in male first-episode schizophrenics.Short-term antipsvchotic treatment with risperidone tablets may have no effects on measures of prefrontal lobe and thalamus.

Objective To identify the metabolic alterations in the prefrontal lobe in male patients with schizophrenia by proton magnetic resonance spectroscopy (~1H-MRS), and to study the relationship between metabolic alterations and executive function. Methods The study was conducted in 26 male schizophrenics with medicine-free for at least 7 days and 28 normal controls. A multi-voxel ~1H-MRS on the prefrontal lobe was performed in all the subjects within 24 hours of admission. Wisconsin Card Sorting Test (WCST) was used to evaluate executive function. The NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho+Cr) were calculated. Results Compared with normal controls, the patients demonstrated significantly lower NAA/Cr ratio (t=2.93, P<0.01) in the left prefrontal lobe and poorer performance in WCST (P<0.05). The NAA/Cr ratio in the left prefrontal lobe was positively associated with the responses errors and the perseverative errors of WCST(r=0.45, P＜0.05; r=0.47, P＜0.05)and negatively associated with the categories completed and conceptual level responses(r=-0.54, P＜0.01; r=-0.56, P＜0.01). Conclusions Abnormalities in neuronal function and/or integrity are present in the left prefrontal lobe of male schizophrenics. The neuron damage in the left prefrontal lobe of male schizophrenic may be the primary cause of cognition dysfunction.

We set up an SYBR Green I real-time RT-PCR method for the detection of genogroup II Norovirus, and this method's primers were encompassed the conservative region of Norovirus II. The limit of the detection was 10(2) copies. The standard curve's linear range was 10(2)-10(6) copies, correlation coefficient was 0.9952, the slope was -2.982, and the intercept was 35.84. This method possessed specificity for genogroup II Norovirus, without any cross-reaction with rotavirus, adenovirus, hepatitis A virus or astrovirus. The coefficients of variation (CV) of the C(t) values of the standard plasmid were 0.95%-1.69% (n = 5) in intra-assay and 0.87%-1.24% (n = 3) in inter-assay. We used this method to detect 30 shellfish samples, and found 3 samples were positive. This method is sensitive, specific and reliable for Norovirus II. It can be used to detect the Norovirus II in the shellfish rapidly.

Objective To compare the metabolic measures on prefrontal lobe and thalamus among schizophrenics with or without mental disorder family history by proton magnetic resonance spectroscopy (1 H-MRS),and to explore the relationship among metabolic measures,clinical symptom,and executive functioning.Methods Thirty-one schizophrenics with schizophrenia family history,21 schizophrenics with the other mental disorder family history,and 78 schizophrenics without mental disorder family history were examined at prefrontal lobe and thalamus by multi-voxel 1H-MRS.The N-acetylaspartate (NAA),Choline-congtaining compounds (Cho),and Creatine compounds (Cr) were measured and the ratios of NAA/Cr and Cho/Cr were determined.Meanwhile,Positive and Negative Syndrome Scale (PANSS) and Wisconsin Card Sorting Test (WCST) were also assessed in all schizophrenics.Results Both in schizophrenics with schizophrenia family history and with the other mental disorder family history,the NAA/Cr ratios showed lower than those in schizophrenics without mental disorder family history both on left prefrontal lobe and on fight thalamus ( P ＜ 0.05 ).Compared with schizophrenics without mental disorder family history,the score of negative symptoms and the perseverative errors demonstrated higher ( P＜ 0.05 or 0.01 ),the categories completed showed lower both in schizophrenics with schizophrenia family history and with the other mental disorder family history ( P＜0.05 ).The NAA/Cr ratios on left prefrontal lobe in all schizophrenics were significantly negatively related with the total score of PANSS and the responses errors (P ＜ 0.05 or P＜ 0.01 ),and positively related with the categories completed and the conceptual level responses ( P＜ 0.05 or P＜ 0.01 ).On left prefrontal lobe both in schizophrenics with schizophrenia family history and with the other mental disorder family history,the ratios of NAA/Cr were negatively related with the score of negative symptoms and the perseverative errors ( P ＜ 0.05 or 0.01 ).Conclusion The damages of neurons on prefrontal lobe and thalamus in schizophrenics with mental disorder family history may be more severe than those in schizophrenics without family history,and the damages on prefrontal lobe are related with negative symptoms and executive functioning.

Objective To identify the metabolite levels in prefrontal lobe and thalamus in patients of schizophrenia with proton magnetic resonance spectroscopy (1H-MRS). Methods Twenty-six schizophrenics with medicine-free for at least 7 d and 28 normal controls were assessed in this study. All subjects underwent examination of multi-voxel 1H-MRS on prefrontal lobe and thalamus within 24 h. The NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho+Cr) were determined. Results Compared with the controls, the NAA/Cr ratio of schizophrenics was significantly lower in left prefrontal lobe and bilateral thalamus (all P＜0.05). No statistical difference of NAA/(Cho+Cr) ratio and the Cho/Cr ratio was found between two groups. Conclusion Abnormalities in neuronal function and/or integrity are present at left prefrontal lobe and bilateral thalamus simultaneously in schizophrenics.

Objective:To compare the efficacy of traditional open thyroidectomy and modified Miccoli in the treatment of benign thyroid diseases.Methods:The data of 343 patients with benign thyroid disease in Xi′an Central Hospital and Xi′an Third Hospital were retrospectively analyzed. According to the surgical method, the patients were divided into the observation group (modified Miccoli operation, n=169) and the control group (traditional open operation, n=174). The operation effect, postoperative recovery, patient satisfaction, postoperative complications and recurrence within 1 year of follow-up were compared between the two groups.Count data were represented by n(%), measurement data consistent with normal distribution were represented by Mean± SD, and non-normal data were represented by M( P25, P75). T test or Wilcoxon rank sum test were used to compare the measurement data between groups according to their distribution characteristics. Comparison of statistical data between groups was made by chi-square test. Results:The intraoperative blood loss and postoperative drainage volume of the patients in the observation group were 26.2 (6.9, 40.8) ml and (33.4±8.6) ml, respectively, which were significantly less than those in the control group 50.6 (37.5, 63.7) ml and (35.7±9.5) ml (all P<0.05). The postoperative recovery time in the observation group was (3.9±2.8) d, which was significantly shorter than that in the control group (5.1±2.4) d ( P=0.001). Postoperative complications such as hoarseness, subcutaneous ecchymosis, scar formation and decreased parathyroid function were significantly different between the two groups ( P<0.05). The recurrence rate of 7.69% in the observation group was significantly lower than that of 19.54% in the control group 12 months after operation ( P<0.05). Conclusions:The modified Miccoli in the treatment of benign thyroid diseases not only has the advantages of less trauma, faster postoperative recovery, less pain and higher patient satisfaction, but also has lower postoperative complications and recurrence rate, which is worthy of clinical promotion and application.
